As Profusion’s consulting team continues to grow, we’re looking for technically minded individuals who are passionate about supporting the systems and infrastructure that power data-driven business solutions. In this role, you’ll be a key part of the team that ensures our consultants—and the clients they serve—have reliable, secure, and high-performing IT environments.

This is a great opportunity to grow your career in systems administration and IT operations, while gaining exposure to cloud-based platforms, enterprise data tools, and client-facing service delivery. You’ll play a vital part in maintaining the tools, access, and systems that allow our data professionals to deliver high-quality work.

Key Responsibilities

As a part of the DevOps and IT team, you will help us manage our on-prem and cloud estate, be a part of our client support team, take a share of our IT work and help to keep us secure.

Key Skills/Experience:

We are looking for people with experience in:
• Administer and maintain Linux systems, with a focus on Debian-based environments, ensuring system reliability, security, and performance.
• Implement and manage infrastructure as code (IaC) solutions using tools like Puppet, Terraform, and Ansible, supporting scalable and repeatable infrastructure deployment.
• Design, deploy, and maintain cloud-based infrastructure, primarily on AWS, to support internal teams and client-facing platforms.
• Monitor and troubleshoot network infrastructure, including routing configurations, VLANs, and firewalls, to ensure secure and stable connectivity.
• Provide day-to-day it support and administration for internal users, including managing Microsoft 365, Teams, and enforcing security policies.
• Diagnose and resolve system and infrastructure issues, collaborating with consulting teams to ensure minimal disruption to project delivery.
• Support onboarding and configuration of client environments, ensuring compatibility with Profusion’s platforms and standards.
• Contribute to process improvement and automation, identifying opportunities to streamline operations and reduce manual overhead.
• Knowledge of a second language is a nice-to-have, but not essential.

Desired Behaviours:

• Bring a fun, collaborative mentality to work every day
• A desire and passion for data. You love learning about different elements of data, honing your craft because you enjoy problem-solving and discovering new things
• A willingness to learn from and teach others, take initiative and grow your career. This role is not for somebody who wants to do the same thing every day
• Openness to challenge and be challenged in how you think, taking feedback as a way to improve rather than being defensive
• Ability to work in a flexible way, adjusting to the needs and requirements of the client and the working environment

We aren’t being biased when we say this role will help you launch your career. Every day, you will learn from and share knowledge with a range of talented, highly skilled and internationally diverse team of colleagues. All of this while embarking on an exciting journey with a pioneering, fast-growing company situated at the heart of London’s Tech City.
